POCKET-CASE FOR TH ERMOMETERS.

SPECIFICATION forming part of Letters Patent No. 658,998, dated October 2, 1900.

Application filed January 11, 1900. Serial No. 1,095. (No model.)

T0 on whom, it ntay concern.-

Be it known that I, WILLIAM A. RANDALL, of Swampscott, in the county of Essex and State of Massachusetts, have .invented certain new and useful Improvements in Pocket- Oases for Thermometers, of which the following is a specification.

This invention relates to pocket-cases for thermometers usedby physicians and others; and it has for its object to provide at a relatively-small expense an asceptic pocket-case which can be conveniently opened at both ends, and thus present a continuous opening, permitting the convenient and thorough cleansing of the case.

The invention consists in theimprovements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a longitudinal section of a pocket-case embodying my invention and a thermometer in place therein. Fig. 2 represents a sectional View showing the body of the case, the thermometer and the detachable bottom-plug being removed. Fig. 3 represents a sectional view of a modification.

The same letters of reference indicate the same parts in all the figures.

In the embodiment of my invention selected for purposes of illustration, a represents the body portion of a pocket thermometer-case, said body portion being a tube of any suitable material, such as hard rubber or metal, open at both ends, so that when disconnected from the parts that close its ends the body will present a continuous openingfrom end to end, enabling it to be readily cleansed.

17 represents a thermometer, the end of which is attached to a cap or head 0, formed with a screw-threaded shank to engage a screw-thread d at one end of the body a.

e represents a plug which is also provided with a screw-threaded shank formed to engage a screw-thread)", formed at the opposite end of the body. As here shown, the pluge is utilized as the means for connecting the device as a whole with a chain g, which is provided with a safety-pin h or other device whereby it may be fastened to a garment.

With the plugs or heads 0 and e screwthreaded to the body portion or case at there is no possibility of the thermometer dropping out of the case when the entire device is supported from a garment, nor can the body portion or case a become separated from the plug or head 6, to which the chain 9 is attached.

It will be seen that the above-described construction provides for a body portion a, which is a section or length of tubing, said body portion being therefore conveniently and cheaply manufactured bycutting into sections a long piece of tubing and then providing the sections with screw-threads. I do not limit myself,however,to screw-thread connections between the bodya and the end parts 0 and e, as the said end parts may be connected with the body portion by means of slip-joints or in any other suitable manner which will permit the detachment of the end parts from the body portion.

I do not limit myself to making the body portion a in one piece, as it may be made in two or more sections adapted to be separated to expose the thermometer; but in all cases the body portion, whether made in onepiece or in sections,will have removable end pieces so that it can be readily cleaned.

In Fig. 3 I show a complete case in which the head 0 is not attached to the thermometer, the latter being independent of said head. The heads 0 and e may have cushions t' t' to bear against the ends of the thermometer.

Owing to the fact that the plugs or heads 0 and e are adjustable relatively to the body portion or case a, they can be so located as to bear gently against the ends of the thermometer to keep the latter from moving endwise in the case.

In the form shown in Fig. 3 the plug or head 0 is provided with an internal socket,as shown, which socket may receive the end of the thermometer, although it need not be secured therein. With either form shown the device may be inverted from the position shown in the drawings, the plug or head 6 removed from the case a, and the case a may then be removed from the head or plug 0 while the latter is held by the fingers and the case removed from over it for cleaning, thus avoiding any necessity for handling the glass tube of the thermometer.

upright when separated from the tubular body, and a head (2 screw-threaded to engage the other end of the body, one of said heads having means for attachment to a seeming device.

In testimony whereo I have alfixed my signature in presence of two witnesses.

WILLIAM A. RAN DALL.
